See it on the paper →The majority of candidates understood how to use the data given to calculate the average size of the cells shown in the diagram. How to convert the measurement from mm to μm was less well understood. Not all candidates displayed working.
— Examiner report, May/June 2025, 0654/41 Q3(a) (Cambridge)
Most candidates were able to calculate the magnification as 1250. Some candidates were not aware that magnification does not have units.
— Examiner report, February/March 2025, 0654/32 Q4(b)(ii) (Cambridge)
Magnification was quite well known. Candidates had more difficulty describing image size. Length and height were often suggested.
